np - Computer Definition

(Number Portability) The capability of keeping the same telephone number when switching carriers or services. It all started with 800 numbers, which led to local number portability (LNP) and later to wireless number portability (WLNP). November 24, 2003 was known as "Cellphone Independence" day because it was the first time in the U.S. that customers in the top 100 metropolitan service areas (MSAs) could move their telephone numbers to a different carrier. In most cases, landline numbers can also be moved to a cellular carrier.

Sentence Examples

Hence, finally, the resultant is expressed in terms of the coefficients of the three equations, and since it is at once seen to be of degree mn in the coefficient of the third equation, by symmetry it must be of degrees np and pm in the coefficients of the first and second equations respectively.

We take a fixed line OX, usually drawn horizontally; for each value of X we measure a length or abscissa ON equal to x.L, and draw an ordinate NP at right angles to OX and equal to the corresponding value of y .

The assemblage of ordinates NP is then the graph of Y.

Y is represented by the length of the ordinate NP, so that the representation is cardinal; but this ordinate really corresponds to the point N, so that the representation of X is ordinal.
